I currently run a server that gets >100 players and at a target tickrate of 33. However, when the server is more full, the server lags down to a tickrate around 10-15 (as seen in net_graph 4). This way, when the server is more empty the tickrate can be higher.
Is there any downside to doing it like this? I could set the tickrate to 11 like some other big servers do and it wouldn’t vary, but is there any reason to lower it it?
